State-of-the-art technical systems, optimized processes, consideration for neighbours: The new processing plant for industrial and commercial wastewater from Saubermacher in Trofaiach presents itself. Chemical and physical processes convert liquid waste such as acids, alkalis and oil-water mixtures into clean water. Microorganisms carry out the final cleaning. Every year, up to 25,000 tonnes of waste can be processed.
Saubermacher has completely rebuilt the CP treatment plant, which was severely damaged in a fire in June 2017, for the treatment of problematic liquid waste according to the highest environmental standards. “Our focus was not only on the use of state-of-the-art technical systems, but also on the needs of our neighbors. We have moved many process steps from outside into closed halls. The exhaust air cleaning system has also been completely renewed and upgraded to state-of-the-art technology”, informed Hans Roth, founder of Saubermacher. According to Zero Waste, the guiding principle of the company, the aim is to utilize as many residues as possible. “In addition to the technology, the know-how of our employees plays a key role,” explained Gerhard Ziehenberger, CTO of Saubermacher. “For example, we use recovered residual components such as waste oil or oily concentrates as a substitute fuel in the cement industry. This saves valuable primary raw materials and lowers CO2 emissions”. After only twelve months of construction the CP treatment plant now starts full operation.
With lime, gravity and bacteria to clean water
The company invested eight million euros in the redesign. This ensures professional disposal for industrial and commercial enterprises in Styria and in the central region of Austria. Every year, around 300.000 tonnes of industrial wastewater are produced in Austria. The CP system is designed to process the increasingly complex liquid waste streams in its individual composition and also flexibly handle short-term volume increases.
All organic and inorganic liquid waste streams can be treated by: neutralization, an evaporation plant, ultrafiltration and biological aftertreatment. The effluents are treated chemically (with lime to neutralize acids), as well as physically (for example, by distilling mixtures or using gravity in centrifuges to separate liquids and solids). In the end, bacteria clean the water to such an extent that they it be re-integrated into the natural water cycle via dischargment into the sewer system.
Additional protection for the environment
Saubermacher also provides enough green space for its facilities. At the location in Trofaiach now bees of the race Carnica have been settled, which are housed in specially designed 1.100 liter waste containers. With ten hives the company makes a further contribution to the preservation of bees and also produces up to 300 kilograms of the finest honey per season.
